Hi I have a problem here. I have a dvr and I'm using 3g wireless broadband. I had set all the setting in the 3g router and I can view my dvr using the same ISP remotely but I cannot view my dvr using other ISP. Can someone help me out? Thank you Calvert

Hello Clavert, can you please share more detials about the configuration you have set in your 3g router. Because, if you have properly setup the router with proper port forwarding.. then it should be accessable from any ISP. regards, Mirza

Is your WAN IP one of the RFC 1918 IP ranges? If so you won't be able to access it remotely. If it isn't then this guide covers port forwarding and testing, and what we need to know if you need further help.
Those are RFC 1918 IP addresses. If those are for the WAN interface (not the LAN interface) then as already mentioned you cannot remotely access your network. If you're unsure, a picture of the status page in question will enable us to tell (you'll need to use an image hosting site and post a link here). You definitely have an RFC 1918 WAN IP, which means you cannot access your network remotely.

Most mobile internet connection providers do not assign public IP addresses, but private ones. With such a private IP address your network or service cannot be reached over the public internet unless you ISP can configure port forwarding for you (which is almost not the case). This also would be an explanation why you can connect to your DVR from the same ISP, still being in the same "private" ISP network where private IP addresses can be routed. Edit:
As the guide Cry Havok referred to explains, your router's or modem's WAN status page is the only place where you reliably can see your WAN facing IP address, in case this information is provided at all. Anything else, e.g. websites like whatismyip.org just show what IP address the internet sees from you, not necessarily your ISP assigned IP address, but could be a shared/proxied/NATed one.
